My invention relates to cataract absorbers and has for its object to provide an enclosed shield adapted to be placed over theeyes of the patient and provided with an electric heating elementwhereby the heat generated in the eye shield willbe utilized in the treatment of the eyes of the patient.

A turtherobjects to provide a switchbox remotely arranged with respect to the shield and adapted to selectively control the heating element within the shield for the treatment of either e e of the patient. Another object of the invention is to interpose a rheostat in the electric circuit and locate it in the switchbox whereby the intensity of the heat developed in the shield may be regulated.

Other objects and advantages reside in the special construction, combination and arrangement of the various elements forming the invention as more fully hereinafter de-' scribed and claimed, reference being had to the accompanying drawings forming part hereof, wherein,

Figure 1 is "a perspective view showing my invention in operative position,

Figure 2 is a bottom plan view of the shield,

Figure 3 is a vertical sectional view there.- through,

Figure 4: is a similar view through the switchbox, I

Figure '5 is a transverse sectional view taken along a line 5-5 of Figure 1, and

Figure 6 is a diagrammatic view showing the electric circuit.

Referring now to the drawings I have shown my invention comprising an eye shield indicated at 5 of a generally rectangular construction and having its bot-tom portion shaped to snugly fit over the eyes of .a patient and having a lower partition 6 recessed slightly inwardly from the bottom edge of the shield and in substantially parallel relation therewith, said partition forming a compartment ther'ebetween and with the upper edge of the shield within which at opposite sides is mounted an electric light bulb 7 supported in suitable sockets 8 having electric connection extending through the sides of the shield. Plates 9 are arranged over the outer ends of the socket through which the electric wires 10 extend to a switchbox indicated at 11 which may be mounted in any suitable position remote from the shield 5. The compartment within the shield is lined with a suitable heat insulation material indicated at 12 ar- ABSORBER.

ranged along the top and sides of the shield so that the heat generated within the compartment, by means of the electric bulb will be directed against the partition 6 which, when arranged in operative position, isdisposed slightly above the eyes of the patient. The

partition 6 preferably is constructed of a suitable heat absorbing light weight metal such as aluminum or the light whereby the heat generated within the compartment may be quickly transmitted therethrough and at the the shield and to which the same is attached I by means of a nut 14 or the like. Access to the bulb 7 is provided so that the same may be replaced when necessary.

Theswitchbox 11 is preferably constructed of insulation material having a coverplate 12 removably fitted thereon and through which extends a pair of switchhandles 13 each handle operating a switch 142 arranged within the switchbox and connected by the wires 10 for the control of one of the bulbs 7 within the shield. A rheostat 15 is also mounted within the switchbox having an operating handle 16 extending therefrom outwardly of the box whereby to regulate the intensity of the heat transmitted to the bulbs. A cable 17 connects the rheost-at with the house current by means of a plug 18.

In the treatment of the eyes of a patient a cloth pad indicated at 19 may first be placed upon the eyes in order to protect the face oi the patient from injury by the edges of the shield and by placing the shield in proper position it is apparent that heat of a suitable intensity may be directed against either eye of the patient by means of the proper 1nanipula tion of the rheostat and switches within the switchbox.

It is obvious that the invention is susceptible to various changes and modifications without departing from the spirit thereof or the scope of the appended claims and I accordingly claim all such forms of the device to which I am entitled;

I claim:

1. In a device oi the class described, an eye shield, a pair of electric light bulbs arranged therein, earh of said bulbs being disposed respectively above the eyes of a patient,

a switch box, and a pair of switch elements arranged therein and connected respectively to the bulbs for selective operation of either thereof and a rheostat arranged in the switchbox and interposed between said bulbs, and said switch elements.

2. In a device of the class described, an eye shield having its lower portion shaped in con mote from the eyeshield, a pair of switch elements arranged therein and connected respectively to said bulbs and a rheostat oper-i ativel-y arranged within the switch box and interposed between said switch elements and said bulbs.

3. In a cataract absorber, an eyeshield having its lower edge shaped to conform with "the contour of the eyes of a person, a partition removablysecured within the shield adjacent the lower edge thereof, a pair of electric light bulbs mounted within the shield,

a heat insulated lining for the top andside,

portions of the shield, a switchbox remote from the ,shield,"apair of switch elements operatively arranged within theboxand connectedrespectively to said bulbs whereby to selectively control the same and an electric rheostat mounted within-the switchbox having an operatinghandle extending therefrom,

said rheostat being interposed between each of said switch elements and said bulbs.

In testimony whereofI aflix my signature.
